Crankshaft pulley bolt

[Mutz]

Ok simple matter is it wont come undone.

Tried it in the 90; as per haynes instructions, plus some one pressing hard on the foot brake, and rear wheels being chocked.Wouldnt move.

Got it out and locked the flywheel tried shocking it, and a 4foot scaffold bar on a rachet and a solid bar, bent them both!!!!!!!

Any more ideas or has anyone else had problems.

its on a 300tdi.

I use a ring spanner and "flog" the nut undone.

[davidlandy]

I undone mine by putting a knuckle bar on the nut then a scaffold bar onto the knuckle bar then tucked it under the nearside chassis.

fuel pump wire off

foot on brake and crank it over a turn ...bingo

Try 3/4 drive socket and bar plus scaffold bar,1/2 too flimsy.

easy way of undoing them  :lol:

1/2" drive breaker bar, fit socket onto end....then put the breaker bar underneath the chassis steering box end so as the breaker bar cannot rotate around
disconnect the fuel stop on the inj pump
then using the torque of the starter, flick the key ( there will be a thud of the breaker bar) and the shock will free the bolt off
just let it crank over a couple of times...saves undoing it by hand  :lol:

just same as what dave said really  :roll:

the engine is out of the def now, :oops:  hindsight is such a wonderful thing!!!!! :roll:

Actually thinking about it now, using the starter was how the mechanic did my Pajero. :shock:

 :idea: So ring spanner and a 14lb sledge hammer and dont miss!!!!!!!

get a mobile mechanic out  
3/4inchdrive impact gun will soon shift it  

i have sat there for ages with a half inch gun with impact socket before now when engines been out, and the shock had broken the seal enough for me to undo it with a big bar

make sure the engine is secure, ( i got tie down points in corner of workshop where i ratchet strap it down)
get someone to hold the flywheel with a prybar and you swing like a monkey off the crank bolt  :lol:

if not, warm it up with some oxyacetyline bottles, itll go then  :shock:

Have tried impact wrench, no joy there, have got a frame support on flywheel and bolted to casing; but engine does move about a bit so will try to get it more firm tomorrow and go buy another spanner or 2 in case i break some more. thanks for your advice, appreciated.

Damn i wish i had rememberd about the starter trick, well cheesed about it now.

if you warm it up be four you shock it should go. i used a 3/4 air gun on mine and didnt shift it warmed it up with some oxi then give it a shock big smack on the cranck bolt with a big hammer it soon came undone

[Mutz]

"Done it"
Think the main problem was not having it fixed down and i was losing leverage.

Droped it onto ramps to hold it firm then used 24" breaker bar with 5' scaffold pole, after 3rd attempt it came free; glad i didnt have to use heat as concerned about the rubber mount in the pulley wheel.

Thanks for all your advice.

the last one i did was on a mitsubushi, 54mm nut, tight as the perverbial.

1" impact gun (nearly take two poeple to lift!), whipped it straight off.
